The growth of Cyanidium caldarium on nitrate and ammonia as nitrogen sources was studied at different temperatures from 21 to 54~ Algal growth occurred at temperatures of 24~ or above when ammonia was the nitrogen source, whereas with nitrate, growth occurred at 30~ or above. The optimum and the ma

The regulation of the development of nitrate reductase (NR) activity in Chlamydomonas reinhardii has been compared in a wild-type strain and in a mutant (nit-A) which possesses a modified nitrate reductase enzyme that is non-functional in vivo. The modified enzyme cannot use NAD(P)H as an electron d
## Summary The effect of constitutive expression of nitrate reductase (NR) on the regulation pattern of nitrite and nitrate transporters (NT) has been analysed in __Chlamydomonas reinhardtii__. Strain Tx11β8, bearing the chimeric __Nia1__ gene for NR under the control of the __cabllβ1__ gene promot
